case they would get added twice).

exactly what bugpoint expected it to do.
There was also only one user of
BlockExtractorPass(const std::vector<BasicBlock*> &B), so just remove it and
make BlockExtractorPass read BlockFile.
This fixes bugpoint's block extraction.
Nick, please review.

it establishes a context and does a complaining diff. Also make sure we
unify the prelude and postlude of a diff after a block-diff call.

any differences we see. This should only happen if there are "non-structural"
differences between the instructions, i.e. differences which wouldn't cause
diff to return true.

in despite not ever incrementing any path costs, so that the only nonzero costs
arose from the all-left path in the first column. Anyway. Perform the diff
starting from the beginning of the block to avoid capturing (say) loads of
allocas.
Vastly improves diff results on code that hasn't been mem2reg'ed.

diff of a function. There's a lot of cruft in the current version, and
it's pretty far from perfect, but it's usable.
Currently only capable of comparing functions. Currently ignores metadata.
Currently ignores most attributes of functions and instructions.
Patches welcome.

ReduceMiscompilingFunctions::TestFuncs. This makes the test functional
(i.e., no side effects).
Before we would end up using dead functions if a pass decided to remove them
(inline for example) and we would also keep broken functions and conclude that
that a single function was enough to reproduce the bug.

arm explicitly. X86 and ARM are the only two targets that support
disassembly, so our explicit list is enough. These other targets
weren't getting pulled in anyway though, since there were no
references to their symbols.

better in the llvm world. Among other things, this changes:
1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
API depends on it.
4. Various code cleanup changes.
There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.

- Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.

DIRS list, so it does no good to filter it from PARALLEL_DIRS), and replace
it with a check to disable building the shared library version of edis when
the flag is set. Disabling it entirely does not work because MC uses it now.

Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.
For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:
.globl l_objc_msgSend_fixup_alloc
.weak_definition l_objc_msgSend_fixup_alloc
.section __DATA, __objc_msgrefs, coalesced
.align 3
l_objc_msgSend_fixup_alloc:
.quad _objc_msgSend_fixup
.quad L_OBJC_METH_VAR_NAME_1
This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".
Currently only supported on Darwin platforms.

having a library both as bitcode and native code. We want to use the
bitcode first, but if codegen produces new undefined references we have to use
the native code to satisfy those references.
Gold has no notion of bitcode and native search directories, so instead it has
an API where the plugin can instruct it to look for the libraries it is passing
to it. This patch uses that API.
